To calibrate your sensor, using outdoor calibration (recommended):
- Leave your sensor outside for 10 minutes, away from any CO2 sources (for example, yourself). Also try to keep it away from excess wind.
- Hold down the left button on your sensor until the LED breathes green. Wait 5 minutes (leave it alone and come back later). That's it! Sensor will resume its previous state automatically when calibration is complete.
To calibrate your sensor with a calibration gas:
Procure Equipment:
- 1000ppm CO2 calibration gas
- regulator (.1-.5 lpm)
- tubing
- funnel
Calibrate with calibration gas:
- Place sensor in upside-down funnel. Plug in sensor.
- Turn on gas.
- Press right button to wake device.
- After waking, press and hold both buttons on sensor until LED alternates between green and orange.
- Wait 5 minutes (leave it alone and come back later). That's it! Sensor will resume its previous state automatically when calibration is complete.
